METHOD OF PROGRAM SYNTHESIS FOR FAILSAFE INTERLOCKING DEVICE IN RAILWAY SIGNALLING

The functions are analyzed of conventional interlocking relay devices used for train control. It is indicated which parts should be designed on the failsafe basis. A method is also proposed for synthesizing a failsafe logic system which is fed with non-failsafe inputs. A universal digital computer program using an interlocking matrix is proposed for the failsafe logic system. The effectiveness of the proposed method has been confirmed by field tests and 20,000-hour test operations.
